Scaevola plant named ‘Bonsca 1419’

ABSTRACT

A new and distinct cultivar of  Scaevola  plant named ‘Bonsca 1419’, characterized by its compact and mounding plant habit; freely branching habit; early and freely flowering habit; long flowering period; light violet-colored flowers; and good container and garden performance.

Botanical designation: Scaevola aemula.

Cultivar denomination: ‘BONSCA 1419’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Scaevola plant, botanically known as Scaevola aemula and hereinafter referred to by the name ‘Bonsca 1419’.

The new Scaevola plant is a product of a planned breeding program conducted by the Inventors in Yellow Rock, New South Wales, Australia. The objective of the breeding program is to create new compact, mounding and early-flowering Scaevola plants with numerous attractive flowers.

The new Scaevola plant originated from an open-pollination in Yellow Rock, New South Wales, Australia in March, 2013 of a proprietary selection of Scaevola aemula identified by the code number 13-16, not patented, as the female, or seed, parent with an unknown proprietary selection of Scaevola aemula, as the male, or pollen, parent. The new Scaevola plant was discovered and selected by the Inventors as a single flowering plant from within the progeny of the stated open-pollination in a controlled greenhouse environment in Yellow Rock, New South Wales, Australia on Mar. 4, 2014.

Asexual reproduction of the new Scaevola plant by vegetative tip cuttings in a controlled greenhouse environment in Yellow Rock, New South Wales, Australia since March, 2014 has shown that the unique features of this new Scaevola plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Scaevola have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Bonsca 1419’. These characteristics in combination distinguish ‘Bonsca 1419’ as a new and distinct Scaevola plant:

-   -   1. Compact and mounding plant habit.     -   2. Freely branching habit.     -   3. Early and freely flowering habit.     -   4. Long flowering period.     -   5. Light violet-colored flowers.     -   6. Good container and garden performance.

Plants of the new Scaevola can be compared to plants of the female parent selection. Plants of the new Scaevola differ primarily from plants of the female parent selection in flower petal color as plants of the female parent selection have deep blue-colored flowers petals.

Plants of the new Scaevola can be compared to plants of the Scaevola aemula ‘Bonscalib’, disclosed in U.S. Plant Pat. No. 19,516. In side-by-side comparisons, plants of the new Scaevola differ from plants of the ‘Bonscalib’ in the following characteristics:

-   -   1. Plants of the new Scaevola are more compact and mounding than         plants of ‘Bonscalib’.     -   2. Plants of the new Scaevola flower earlier than plants of         ‘Bonscalib’.     -   3. Plants of the new Scaevola are more freely flowering than         plants of ‘Bonscalib’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Scaevola plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Scaevola plant.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Bonsca 1419’ grown in a container.

The photograph at the bottom of the sheet is a close-up view of a typical flowering plant of ‘Bonsca 1419’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the late summer in 20-cm containers in an outdoor nursery in Higashiomi, Shiga, Japan and under cultural practices typical of commercial Scaevola production. During the production of the plants, day temperatures ranged from 15° C. to 30° C. and night temperatures ranged from 13° C. to 25° C. Plants were three months old when the photographs and the detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
